Question 11 Not yet answered Marked out of 1. Right whales, hunted to near extinction, were easy prey because their maximum velocity is a relatively slow 4.8 km/h [forward]. What is the mass of a right whale swimming at its maximum momentum of 2.67 x 104 kg.m/s [forward]? O a. 7.2 x 104 kg O b. 5.6 x 103 kg O c. 3.3 x 105 kg O d. 2.0 x 10* kg Clear my choice Question 12 Not yet answered Marked out of 1.00Question 12 Not yet answered Marked out of 1.00 A 550 g basketball in flight has a velocity of 4.18 m/s [W] at the top of its are. At that point it is struck by a 58.4 g arrow flying at 38.2 m/s [60.0 N of W]. The arrow becomes lodged in the ball. What will be their combined velocity immediately after the arrow becomes stuck? O a. 3.92 m/s [29.50 N of W] O b. 3.92 m/s [29.5 W of N] O c. 6.45 m/s [29.50 N of W] O d. 6.45 m/s [29.5 W of N] Previous page Next page Data Sheets Jump to...

By increasing the voltage between the plates to 1.50 x 102 V, the sphere was eventually suspended between the charged plates. The strength of the electric field between the plates is a.box 10 N/C. The values of a, b, c, and d, respectively, are and . (Record all four digits of your answer in the space provided.)
